@Eddy63 yeah they aren't cheap but very much worth it though. Thanks for stopping by

@@FroggieBeluga pretty much. As the guy put it electromagnetic saturation.

@@EverythingHVACR 425 tons. 1194lbs of 134a

Just a little guy, lol.

​@@fshn76 just a wee little lass.

Sorry Steve-o I didn't read your question correctly. In the mechanical room is probably 1200 tons. This chiller is 425

@ all good brother, I appreciate you.

@EverythingHVACR thanks brother. Hope the new gig is going well.

@ right back at ya brother, we’ll have to catch up again soon.

@@petermuller161 all truth

@@MrApplied this subcooler has ⅜" port adapters with ¼" connectors, one ¼" port adapter with ¼" connector. Used 56% silver brazing rods. Does this answer your question?

@ yes but also like you think I can get this on eBay maybe?

@fshn76 yeah it was shaking pretty good. I shut it down and let the building know it wasn't recommended to run.

@@neilcvids2583 it was 37° that morning

22 this morning in N Georgia

@@neilcvids2583 Happy Thanksgiving to yall

@FroggieBeluga it was a shaking like a disco in the 70's 😆 🤣

I was thinking that or possibly a hub issue. You can definitely hear those blade tips hitting the shroud

I didn't dig into it, as it was the end of the day on Wednesday. Its off for now.

@jeffreyrex8232 im not sure why the timer is set that high. Megger testing is just a part of routine maintenance of who i was employed with at the time. I have to do the same thing where im employed now as well on annuals.

@@EmmanuelShahid7 i would start by confirming you have water and that the pump works. You can jump out the pump contacts.....after you confirm there is water in the loop. I don't always trust analog gauges in a hydronic system.

@jasonjohnsonHVAC thanx bro I will take a look at it. I work at the VA BOILER and working 2 month. they were using the regulater valve with the little handle to maintain at 30 to 35 psi. I check last night was running fine but was around 45 psi which was a concern. I came in tonight and it was down. water circular pump was running but no pressure at all. I tried resetting a few time on the copper fin side and turning it on and off and no luck. I will try your method as you mentioned.

@@FrankBenlin 😆...thought did cross my mind though

@icicle_man4971 this ductwork is for labs. The equipment keeps the labs at precise temps, humidity and pressure for what is needed

@@blaydCA 😆

@Blakethegoat proper maintenance and they run like a champ.

@Hammerthumb1 not semiconductor, but bioscience labs

I knew it was clean room after his 2 second pan of the "plenum" area.

@@BasedBidoof my thoughts exactly when I seen it

@chriswalford4161 it is injected from the humidifier itself. What i like about this one is there is no canister to replace. It has a stainless steel box where the heaters are. It's a fairly simple unit mechanically.

@@mysock351C 😆😆

@@projectartichoke there is a kit for it, which has been installed

@@projectartichoke i was told it took 8 months for just the ductwork alone. They have to have the airflow balanced and certified every year. It's pretty impressive

And an army of inspectors.

@bigcatauna lol...it has to be checked and certified every year.

Its actually relatively easy when it comes to these places because everything is close to spec and acessible. I say relative because the hardest part about air balancing these is having to go into clean room environment.

@@ElonMusk-hx8yw i wouldn't ever want to be an insulation tech....I definitely wouldn't have wanted to to this job either.

@@KennytheHedgehog619 banished to the depths of hvacland

@Jonas_Keunecke whoever installed it and wrapped it did a really good job. It looks professional. Appreciate you stopping by and checking out the video

@@theonecommenter secret poker games and brothel.

@@Majilikin hahahaha....thats was a good one

Im that took awhile to do

@@ziggymartinez2273 it was done nicely. I was told all that ductwork alone took over 8 months to do.

@@sparkplug1018 hahahaha it is easy to get lost if you are looking for something specific. Bioscience building so many different types of piping for various different types of uses

@shockingguy panels for labs that are pressure dependent. Some are positive, some are negative pressure.

@heathhill7802 its a bioscience facility. Many different labs with positive or negative air pressure. It's interesting

@@jasonjohnsonHVAClooks pretty much the same as semiconductor clean rooms.

@Epiccatsandkittens there are 90 and 60 ton rooftops. I believe this roof for all those labs there were 6 RTU'S up there. Not just a conventional rtu. I have a previous video where I replaced a trio set of compressors on a 90 ton
